Short term energy monitoring: a road to long term energy savings? Available to Purchase

Engineers at the Energy Systems Laboratory at Texas A&M University conducted short term energy metering studies at a complex of offices in northern Texas and several buildings on the Texas A&M University campus. These studies typically consisted of installing electrical metering at the whole building level and included sub‐metering of selected circuits when possible. A staged shut‐down sequence was performed for all lighting, fan, and mechanical systems of interest in the facility. Lighting system load verification was the primary goal. The study was a follow‐up to an earlier lighting study that had been conducted by the campus energy office. Base electrical load data were also determined from these tests, and in both studies significant “base” electrical loads were found. This paper presents results of these studies and suggests that the method is attractive to both contractors and facility energy managers as well.
